We're dividing 26309238 by 12 
The aim is to understand the frequency of 12 in 26309238.

On to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 12

Moving on to step 2:
If we divide 26 by 12, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 24 from 26 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

On to step 3:
When dividing 23 by 12, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 11 after subtracting 12 from 23.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 12

Going ahead to step 4:
If we divide 110 by 12, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 219.0
Deduct 108 from 110 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 12

Moving on to step 5:
If we divide 29 by 12, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2192.0
Subtract 24 from 29 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 12

On to step 6:
12 goes into 52 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 21924.0
If we subtract 48 from 52, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

Going ahead to step 7:
12 goes into 43 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 219243.0
If we take 36 away from 43, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 12

Let's proceed to step 8:
78 divided by 12 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 2192436.0
Subtract 72 from 78 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
12 goes into 60 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2192436.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2192436.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2192436.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 2192436.5 with a remaining 0.0.
